Definitions

  • This invention relates to the management of water consumption within a specific area, such as an apartment, a building or more generally an area that includes several end points where water is distributed.
  • Water consumption measurement is well known. Generally, there is one single point of metering located at the entry point of the building. This arrangement generates rough data, does not enable consumers to get real-time feedback locally or at any point of use, actively monitors their consumption globally and then adapt the behavior of the house inhabitants accordingly. With one single measure, water providers cannot i) invoice precisely the water consumption per apartment, ii) infer the demand/consumption trends with precision of an area of buildings under management for planning / forecasting purposes, reducing headroom advantageously.
  • the present invention improves the water consumption management by departing from the conventional approach of measuring water demand at a single point (i.e. the water entry) in an area comprising several end points and at sporadic intervals. Instead, according to the invention, water demand may be continuously metered and monitored at each end point where water, hot or cold, is distributed.
  • the invention concerns a water consumption management system for a specific area, such as an apartment, a building or more generally an area that includes several end points where water is distributed; said system comprising an interconnected network of sensors that are adapted to measure water consumption at each end point; said network being connected to a data processing unit and to at least one display element that provides an information on the water consumption at each end point of said specific area wherein at least some sensors comprise each a turbine arranged to measure first flow rates and a rotating piston arranged to measure second flow rates, wherein the second flow rates are higher than first flow rates, and wherein said turbine is located in the center of the rotating piston.
  • the system according to the invention is based on a network of sensors (e.g. IoT devices) measuring the water consumption, for instance the water output of each tap, the water input of dishwashers, washing machines, head showers or flushes, i.e. on any water endpoint of the building. More generally, the sensors used in the present invention can measure any water end point of interest, detect leaks by either detecting abnormal activity such as a leaking faucet or simply comparing their nonactivity with the single-entry meter's activity.
  • sensors e.g. IoT devices
  • This setup advantageously allows data analytics on water consumption to help the house inhabitants to adapt their behavior to reduce their water needs and prevent flaws and damages.
  • the system can be used either in a standalone mode where the users obtain an immediate feedback locally on each device with the volume and the temperature of the water they consume or in a remote mode where the users obtain a consolidated view of the consumption used through the devices installed on the outputs, both at any point of time.
  • the system illustrated on figure 1 comprises a set of IoT sensors (101 to 107).
  • the user can precisely monitor the volume flowing through each water end point and see the data displayed at each point of use such a kitchen tap. Knowing the temperature of the water, the algorithm can compute the energy required (kWh) to bring cold water to the desired temperature with very high precision over the time, provided cold-water temperature has been calibrated at set-up. This information can be very useful to pilot the heating processing of the boiler as the system can transmit to it when hot water will be required or not.
  • a sensor according to the present invention can be used in different manners, e.g.:
  • the system measures and displays the use at each end point with indication of the temperature.
  • the system (100) includes:
  • data recorded from the adapters (101 to 107) may be sent to an electronic computing device (108), such as a mobile phone, tablet, laptop computer, desktop computer, smart TV, smart TV adapter, Voice assistant like Google Home or Amazon Alexa, music player and/or any other computing device with network connectivity.
  • an electronic computing device such as a mobile phone, tablet, laptop computer, desktop computer, smart TV, smart TV adapter, Voice assistant like Google Home or Amazon Alexa, music player and/or any other computing device with network connectivity.
  • a user may access various statistics in the installed app from one or more water usage (e.g. shower session taken by the user) or at a dwelling of the user. These statistics may include, for example, the length of a shower (time), a volume of water used during the shower, and/or an average temperature and energy equivalent (KWh) of the water used during the shower.
  • data may be collected and plotted on a temperature scale between 32° degrees Fahrenheit (0 degree Celsius) and 212-degree Fahrenheit (100 degrees Celsius), and within a reasonable range of 50 degrees Fahrenheit (10 degrees Celsius) and 150 degrees Fahrenheit (65.5 degrees Celsius).
  • data may be plotted and displayed on a mobile device showing flow between 0 gal/min (0 liter/hr) and 22712 liter/hr (100 gal/min), within a reasonable range of 454 liter/hr (0.2 gal/min) to 4542 liter/hr (20 gal/min) .
  • data may be communicated to the device regarding the total volume of water that has been used (e.g. 104,56 liters (23 gallons)) and the total duration of the shower (e.g. 8 minutes).
  • the total volume of water that has been used e.g. 104,56 liters (23 gallons)
  • the total duration of the shower e.g. 8 minutes
  • the amount of money spent on a water and/or heating bill may also computed and displayed to the user.
  • the amount may be extrapolated to yield an approximation of daily, weekly, monthly and/or yearly utility bills.
  • real time data from a user's utility bill may be inputted manually by the user or automatically populated from a utility bill paying account associated with the user or the physical address at which the devices are used.
  • the application may incorporate a database including local utility providers as well as standard utility costs associated with a given geographic region.
  • the application and/or the device may communicate directly with the municipality or utility company in addition to our machine learning cloud-based server (109).
  • the utility company may be able to offer real-time incentives and savings to consumers for reducing their utility costs.
  • the utility companies may receive incentives, grants, and/or other funding from local or federal government for reducing water consumption thereby reducing greenhouse emissions and a resulting ecological footprint.
  • the machine learning cloud-based server (109) is implemented to compute time series predictions (LTSM), but not only, to collect, analyze and automatically derive a water usage model which can be a statistical model of probability of a water draw vs. time or a suitable supervised machine learning algorithm or any other advantageous algorithm. Then, it can derive approximately an electrical consumption model (kWh) required to heat a specific volume of water at a given temperature) from previously acquired water usage data.
  • the system is capable of actively monitoring and recording the building's water usage patterns to allow the consumer (i.e. homeowner or business or any entity exploiting a building or a facility) to adapt his behavior regarding his consumption profile, assuming that the consumer has installed the sensors at least one or at each point of water use like dishwasher, shower, laundry machines, flushes or any other point of interest.
  • Other information can also combined with the consumption data. This includes local weather, building occupant's calendar or any other information useful to mine the usage figures. For example, weather information can affect water usage since individuals will need more water during summer or hot water during winter or cold seasons. If the profile of the home's occupants is updated by the user in the App (108) (e.g. a new occupant, a new laundry machine, etc.), the algorithm can adapt the clustering of the consumer (i.e. from couple to family) or recommend consumption objectives adequately to the usage profile based on the peer benchmark.
  • Another interaction between the sensors and the app (108) enables enriching additional information provided by the smartphone, such as positioning data given by its GPS chip in order to determine the area of the building, its context in terms of water sourcing (e.g. hard or sweet water area) and any other enriching data.
